Troubleshooting the MX960 MPCs
Problem
Description
The MPCs are not functioning normally.
Solution
Monitor the green LED labeled OK above the MPC on the craft interface as soon as an MPC is seated in an operating router.
The Routing Engine downloads the MPC software to it under two conditions: The MPC is present when the Routing Engine boots Junos OS, and the MPC is installed and requested online through the CLI or push button on the front panel. The MPC then runs diagnostics, during which the OK LED blinks. When the MPC is online and functioning normally, the OK LED lights green steadily.
Make sure the MPC is properly seated in the midplane. Check that each ejector handle has been turned clockwise and is tight.
Check the OK/FAIL LED on the MPC and OK and FAIL line card LEDs on the craft interface. When the MPC is online and functioning normally, the OK LED lights green steadily.
Issue the
show chassis fpccommand to check the status of installed MPCs. As shown in the sample output, the value Online in the column labeled State indicates that the MPC is functioning normally:user@host> show chassis fpc Temp CPU Utilization (%) Memory Utilization (%) Slot State (C) Total Interrupt DRAM (MB) Heap Buffer 0 Online 36 3 0 2048 14 13 1 Online 40 5 0 2048 26 13 2 Online 41 6 0 1024 7 43 3 Online 43 5 0 1024 16 57 4 Online 24 3 0 1024 13 21 5 Empty 6 Online 43 5 0 1024 16 57 7 Empty 8 Empty 9 Empty 10 Online 24 3 0 1024 13 21 11 EmptyNote:The
